Buggy Fit is an exercise class devised for postnatal Mums with a baby in the pram or buggy. Our Personal Trainers have become very good at rocking the odd pram or two whilst Mums work out!

Having a baby can create a life absorbed with ‘baby activities’ and clinic visits, but studies show taking time out for yourself, especially fitness, results in a better mental state, relieving stress, improving stamina and core muscles and creating a happier you.

Parking is on site at Herts & Essex Sports Centre, making the journey from the car to the gym with baby in tow a pleasantry, with the added addition of the onsite coffee shop. Mum’s can grab a coffee, feed their babies before they head home and socialise with any new Mum’s they may have met at class.

All Buggy Fit trainers are fully qualified and insured fitness professionals, who are trained to understand what a new Mum’s body has been through and devises training for each postnatal stage. Incorporating cardiovascular and fat-burning exercises with strength training and toning exercises, concentrating on specific areas post pregnancy.

A 45-minute window, following the PT schedule which was devised for free when we joined. It is so refreshing to be able to train without the glances from passers-by and the team are always on hand to help out if we are not doing anything correct.
